Answer 1

I have 2 idea:

1. Try to run npm install -g @angular/cli
2. In case you will have error: did you run it from power shell or command line? Cause I had a problem with "ng new app" from power shell, but in a command-line it was correct

Answer 2

Dou you have problems with your internet connection?

From your error, which says

ERR! request to https://registry.npmjs.org/@angular%2fcli failed, reason: getaddrinfo EAI_AGAIN registry.npmjs.org

It seems as though internet connection is low, or restricted.

Try looking at this answer to solve your problem.

Answer 3

First, of all check, your internet connection is working or not. And if there is no problem with the internet then use below command

$ npm cache verify

$ npm cache clean --force

and then try again.

If you still get the error then use the yarn package manager. Install yarn by running this

$ npm install -g yarn

and then configure angular cli to use the yarn package manager, by running this command

$ ng config -g cli.packageManager yarn
